hi,

how do i solve the following?

restart:

ode:=diff(y(t),t$2)+y(t)=piecewise(t in [0,Pi],t, t>Pi,Pi);

ics := y(0)=0, D(y)(0)=0;

dsolve({ode,ics});

Thanks

Hi,

Is there something like

assume(a,'nonzero');

how could i tell maple that

a

is a nonzero constant?

Thanks

Hey,

I am doing some ODEs and I met the following problem...

The original problem is

y(x)*(y(x)-2*x)*diff(y(x),x)=1;

and knowing the solutions contains efr function.

After several lines of calculation I got

Int(y^2*exp(1)^(y^2),y);

then maple gives me the answer

1/2*y*exp(y^2)+1/4*I*Pi^(1/2)*erf(y*I)

Hey

Can someone have a look at this

restart:

int(-m*(m-2)/(-1+m^3-2*m^2),m);

maple gives me

-sum(_R*(_R-2)/(3*_R^2-4*_R)*ln(m-_R),_R = RootOf(-1+_Z^3-2*_Z^2))

what dose this imply?

Thanks in advance

Hi,
